I am trying UGUI for my project (working with USB 8 relay board which has CLI interface). I am not a software dev anymore, my experience in programming is long past its expiration date, but I am willing to give it a try. I created a simple index.htm (just like in the ugui.io homepage video for 1.0 version) and it seems to be working, but there is no developer's toolbar at the bottom of the app, so I am unable to debug. <body class="dev"> is in place. What else have to be done for the toolbar to appear?

The official subreddit for UGUI, an open source project on Github. UGUI stands for Universal Graphical User Interface. It exists as a way to allow people to create GUI applications for programs that use command line interfaces (CLI).
